OK, 2005 NA 6speed coupe, daily driver with a year old Optima battery, the battery light just came on today. Was fine on the drive to the store but light came on when I cranked up. Got here turned off car and restart and light still on. Belt looks good, no squealing, 169k on the car so bad alternator or does the car have a voltage regulator too? To pull the alternator any surprises or a direct swap?

thanks
Dan
